What is the impact of running NM cable too close to the edge of studs?

Increased power loss
Improper grounding
Potential damage to the cable
None of the above

The correct answer is: Potential damage to the cable

Running NM (non-metallic) cable too close to the edge of studs can potentially damage the cable. When NM cable is positioned near the edges of studs, it becomes vulnerable to nicking or abrasion from the sharp edges of the lumber, especially during installation or if the framing shifts over time. This type of damage can compromise the integrity of the cable's insulation, leading to potential electrical faults, shorts, or even fire hazards. It's important to maintain proper spacing for NM cable during installation to ensure it is protected from physical damage. This not only safeguards the functionality of the electrical system but also upholds safety standards that are critical in residential electrical systems. Proper installation practices, including keeping cables away from sharp edges, are essential to prevent such risks.
